Progressive care units: different but the same.
Progressive care units are increasingly common in hospitals in the United States. These units are often used to bridge the gap between intensive care units and medical-surgical units, with the goal of providing cost-effective, high-quality, safe care. Although progressive care units today may seem to provide care for a wide variety of patients, these patients do share certain typical features: ...
متن کاملSynthesis of disaccharides containing 6-deoxy-α-L-talose as potential heparan sulfate mimetics.
A 6-deoxy-α-L-talopyranoside acceptor was readily prepared from methyl α-L-rhamnopyranoside and glycosylated with thiogalactoside donors using NIS/TfOH as the promoter to give good yields of the desired a-linked disaccharide (69-90%). Glycosylation with a 2-azido-2-deoxy-D-glucosyl trichloroacetimidate donor was not completely stereoselective (α:β = 6:1), but the desired a-linked disaccharide c...
متن کاملBiological mechanisms involved in the formation of deoxy sugars. VII. Biosynthesis of 6-deoxy-L-talose.
The over-all reaction yielding tbymidine diphospho (TDP)6-deoxy-L-talose was first established using crude enzyme preparations catalyzing Reactions 1,2, and 3. Unambiguous proof for the formation of the L isomer of 6-deoxytalose was provided by radioisotope dilution experiments. Purification of sonic extracts of E. coli 045 into fractions catalyzing individual steps of the above scheme revealed...
متن کاملunits in $f_{2^k}d_{2n}$
let $f_q d_{2n}$ be the group algebra of $d_{2n}$, the dihedral group of order $2n$ over $f_q=gf(q)$. in this paper, we establish the structure of $u(f_{2^k}d_{2n})$, the unit group of $f_{2^k}d_{2n}$ and that of its normalized unitary subgroup $v_*(f_{2^k}d_{2n})$ with respect to canonical involution $*$ when $n$ is odd.
متن کاملModeling the impact of interventions against Acinetobacter baumannii transmission in intensive care units
The efficacy of infection control interventions against Acinetobacter baumannii remains unclear, despite such information being critical for effective prevention of the transmission of this pathogen. Mathematical modeling offers an alternative to clinical trials, which may be prohibitively expensive, unfeasible or unethical, in predicting the impact of interventions. Furthermore, it allows the ...
